A compromised account started sending out spam overnight, causing delays in e-mail delivery starting around 11:30 PM last night and lasting until this morning around 10 AM.
Due to issues with Blackberry e-mail delivery notifications, on-call staff did not get alerts to the problem last night and only received the notification around 6 AM.
CCS started responding to the problem shortly after 6AM and by 10AM the problem has been cleared.
One website seems to have blocked us (comcast.net). We are investigating this and will take necessary measures to correct the problem.
We apologize for the service disruption.
